Hello,
I have recently been trying to test a few things sensor wise in advance of our next regional, but I cannot seem to get the MaxBotix Sonar sensor to work, everything seems to be fine by multimeter, but I am not actually able to read a voltage in C++ using GetVoltage() or GetAverageVoltage(), I assume either one of these would probably work for my desired function.
How the sonar is wired/plugged into the analog card in slot 1:

As for the actual code:
Declaration:
AnalogChannel *Sonar;
double voltageSonar;
Construction I have tried two different ways, neither have worked.
Sonar = new AnalogChannel(1, 8);
Sonar = new AnalogChannel(8);
Inside TeleopPeriodic I have tried:
voltageSonar = Sonar->GetVoltage();
voltageSonar = Sonar->GetAverageVoltage();//Only used one of these, but are both methods I used for testing.
//---------------------
SmartDashboard::PutNumber9"Voltage: ", voltageSonar);
I know that I still have to scale the voltage, but I actually need to read a voltage in order to do so... Does anyone have any ideas as to what I am doing incorrectly?
Thanks!
